摘要

Response surface methodology was employed to optimize the forward extraction of soy 11S globulin using sucrose-enhanced reverse micelles (RMs). Under optimal conditions (sucrose 0.012 mol/L, W0, 18, pH 8.0, KCl 0.17 mol/L, 45 °C, 30 min, solid/liquid ratio 2.5 g/L), the extraction yield reached 76.07%. Compared with alkaline extraction-isoelectric precipitation, the RMs-sucrose method significantly improved protein purity (96.81%), solubility (100%), emulsifying activity, foaming properties, water absorption (2.80 g/g), and oil absorption (4.78 g/g). While surface hydrophobicity and emulsifying stability were reduced, the RMs-sucrose systems system preserved protein structure and modified surface properties, enabling superior functional performance. This approach demonstrates potential for scalable extraction of high-functionality soy 11S globulin.
